Negative. Citizen to Citizen does not require FFL transfer. Only BUSINESS to Citizen or if you send it through UPS. The states have no more right to regulate a gun sale between two private citizens than they do the sale of a book or magazine. It's private property (NOT COMMERCIAL) by that point and the government is out of the picture then.

Gravity, do you know what 80% receivers are? They don't even have serial numbers and they are totally legal.

A company in BC (Canada) used to sell them. Not difficult in Canada to finish them off... But I had thought that in the USA the barrels are also regulated with a serial number and all? (I admit that I may have been misinformed.)

Only the Receiver and fire control parts constitute the gun in the USA. That is why people buy AR's. You can have one receiver but slap on many different uppers to create different rifles. SBR's are only regulated if mated to the lower but most guys just keep them detached. It's all a dog and pony show. Even 400 million guns is what is guessed at. In reality it's much more. Gun regulation in the USA is not possible. That horse left the stable long ago.

And then there is 3-D printing. It's flat-out pointless to enforce the laws at this point. All that can happen is a Supreme Court challenge, and with the setup now it wouldn't go the gun-control nuts way, and own't for the next 40 years.

Same guy who released the 3-D printing files sells a CNC lathe to make lowers for just over $1000. The horse has left the barn.
